After doing a little web browsing, it seems that Gotek has adapted the
Artery AT32F435 MCU on their newer units.
This is a huge improvement over the STM32F107 used on these originally.
288MHz, lots of flash 384KB SRAM. Looks to be a souped-up crossbreed of
the STM32F4 and F7 MCUs.

There's also a German fellow who has done a read-only MFM USB controller
using, of all things, an AVR with just enough memory to hold a single

think). Probably slower than tar in Siberia, however. And it doesn't

Presumably, NEC's FIRST external USB drive used a general purpose USB floppy
